Can I buy a Fizz phone and use it with a different provider?
Fizz phone is unlocked so you can buy and use it with a different carrier
As Luckyy said, Fizz phones are unlocked so you are free to do what you want with them.
All phones in Canada must be sold unlocked. If you are paying full price for a phone with FIZZ then you can buy it and use it elsewhere. If you are receiving a discount, you must maintain an active mobile plan for a fixed period of time (typically 12 or 24 months).
Not sure why you would want to go anywhere else, FIZZ is AMAZING!
